In this paper, it is proposed to develop the fault diagnosis system using the principal component analysis (PCA) for the intelligent operation support system that calculates the effect of fault propagation in abnormalities situation and gives appropriate information to plant operators. This proposed system using PCA discriminates a failure of equipment based on process variables. The proposed m...

Accidents involving rotating equipment in chemical, petrochemical, petroleum, and gas plants can result in damage to other process equipment and catalysts along with lost production. Conversely, process upsets, process instrumentation failure, or failures of other process equipment can result in damage to rotating equipment. An effective rotating equipment loss prevention program will be an int...

This paper presents an analytical method for evaluating the throughput of a production line composed of two reconfigurable machines separated by a finite capacity buffer. This means that each machine is composed of essential and non essential equipment. The failure of any essential equipment induces the shutdown of the entire machine. The failure of the non essential equipment implies the conti...

in this paper we focus on a continuously deteriorating two units series equipment which its failure can not be measured by cost criterion. for these types of systems avoiding failure during the actual operation of the system is extremely important. in this paper we determine inspection periods and maintenance policy in such a way that failure probability is limited to a pre-specified value and ...

Substation refurbishment planning was traditionally initiated by deteriorated network performance indices and the physical observed state of the network. However, it can also be too late, resulting in deteriorated customer service and unnecessary company risk. A Plant Health Index is developed, to understand and assess the condition of equipment during its life cycle. The plant health index wil...

In order to accurately describe and explore the relationship characteristics between faults of numerical control equipment identify weak links in reliability, a new method for associate...
